WebIn order to get things running, you need to install all these three and put them into your Stata ado-path. reg2hdfespatial.ado. The way to call the function is simply as ols_spatial_HAC, … Webdropvar: Drops variables that Stata would drop due to collinearity. This requires that an additiona regression is run, so it slows the code down. For large datasets, if this function is called many times, it may be faster to ensure that colinear variables are dropped in advance rather than using the option dropvar.

But as I said, s.e.s only robust to heteroskedasticity seem more sensible in a VAR, as remaining serial correlation should, in my view, be captured through extra lags in the VAR. $\endgroup$
